Low Voltage Power Transformer Test System

Test system for 1-Phase and 3-Phase Power Transformers with one time connection for all tests.

Sine Inverter Power Supply for Transformers up to 2000kVA

With the innovative and efficient frequency converter technique, a sinusoidal output voltage with low harmonic is generated.
The output frequency range is 50-400Hz, this allows AC induced voltage tests. The wide voltage and current range and the precise regulation are the ideal solution for routine testing of power transformers.

Comfortable Operation and Reporting

Solfas Test Suite 2 software for TTS1000L series guarantees a maximum of flexibility and a minimum of interventions to keep the test duration as short as possible.

After transformer connection the TTS Transformer test system is completely operated via a control unit PC. This allows safe, quick comfortable testing from remote. Test plans for each transformer type allow the exact repetition of individual test sequencences. Test reports are automatically generated and stored.
The TTS1000L makes transformer testing easier, faster and more safe.
